Method for Producing Combustible Gas from Carbon Dioxide and Oxyhydrogen Gas

ABSTRACT

A new combustible gas is produced by reacting a gas mixture consisting of 90%-10% of carbon dioxide and 10%-90% of OHMASA-GAS under a pressure of 0.1 MPa-10 MPa at a temperature of 5° C.-50° C.

FIELD OF THE INVENTION

The present invention relates to a method for producing combustible gasby reacting carbon dioxide with oxy-hydrogen gas generated from water.

RELATED BACKGROUND ART

Nowadays carbon dioxide is nominated as the most influential factor ofthe global warming. However, since there are no effective methods toprevent the carbon dioxide from increasing and no effective industrialmeasures and technical methods to convert the carbon dioxide into otherreusable compounds, concentration of the carbon oxide on the earth hasbeen more and more increasing as the world economy has been developed.Adverse effects on the global environment caused by the increasingcarbon dioxide are far beyond our imagination. Crises which jeopardizehuman lives, for example, such as abnormal weathers caused byatmospheric warming, high tides caused by ocean currents flow changes,adverse effects on ecological systems, draughts and floods, submergedlands by seal level rises, food shortages caused by law yields ofagricultural products and so forth, are too many to enumerate. Thereforeit is an urgent issue to keep the carbon dioxide from increasing byreusing the carbon dioxide.

The inventor (OHMASA, Ryushin) already succeeded in obtainingoxy-hydrogen combined gas, which is safe and different from conventionaloxy-hydrogen gas, by electrolyzing water under specialized vibratoryagitations (hereinafter the oxy-hydrogen combined gas by the inventor iscalled as “OHMASA-GAS” in order to distinguish from the conventionaloxy-hydrogen gas). During the electrolysis, nano-micro bubbles (finebubbles formed by oxygen and hydrogen) are generated by vibratoryagitations, and the generated nano-micro bubbles burst, as a result theburst bubbles converted into the oxy-hydrogen combined gas (see patentreferences 1-3). Since this combined gas contains H₂O clusters (seenon-patent reference 1), it is confirmed that the combined gas does notexplode so that it is safe, while the conventional oxy-hydrogen gastends to explode.

The inventor confirmed a fact that when the OHMASA-GAS is used inwelding, fusing, brazing or the like, it is possible to reduce costs by60-70% compared with cases where acetylene or propane gas is used (seepatent references 2, 3). And it is reported that when power is generatedby a gas mixture consisting of 50% of OHMASA-GAS and 50% of LP gas,costs are reduced to almost half compared with 100% of LP gas, andadditional investment is required little (see non-patent reference 1).

Effects Attained by the Invention

Since carbon dioxide is able to be reduced by using carbon dioxideeffectively as claimed in the present invention, it is possible tosuppress the global warming. And since OHMASA-GAS is able to produce byutilizing inexpensive late-night power, the new fuel gas by the presentinvention is able to produce at low cost.

It is a great discovery on the global scale to discover the fact thatcarbon dioxide excessively exists in the atmosphere can be used in thenew fuel.

Preferred Embodiments by the Present Invention

Carbon dioxide in the atmosphere, generated by combusting substances andthe like may be used as raw materials for the new fuel gas by thepresent invention. The carbon dioxide is not specially designated, butany ordinary carbon dioxide may be used.

However, as “oxy-hydrogen gas”, the conventional oxy-hydrogen gas (whichis not reactive with carbon dioxide) may not be used, but the inventor'soxy-hydrogen combined gas (namely OHMASA-GAS) obtained by the methodsalready protected by patent rights by the inventor (see patentreferences 1-3) should be used in order to react with carbon dioxide.

Hereinafter embodiments of the new fuel gas produced by reacting carbondioxide with OHMASA-GAS and combustion test results of the new fuel gas,are explained.

Embodiment 1

After a high pressure glass tube with a diameter of 100mm, a height of800 mm and capacity of 6.28 liter is vacuumed (gauge pressure −0.1 MPa),OHMASA-GAS is filled in the high pressure glass tube up to 0.3 MPa(gauge pressure), then carbon dioxide is filled in the high pressureglass tube up to 0.8 MPa (gauge pressure). The gas mixture in the highpressure glass tube is compressed up to 1.5 MPa (gauge pressure) by acompressor. No liquid such as waterdrops and steam are observed in thecompressed high pressure glass tube, so that only gaseous substanceexists in the high pressure glass tube.

Embodiment 2

As a combustion test, the compressed gaseous substance obtained inembodiment 1 is burnt by a burner, 15 minutes after the gas mixture iscompressed. In the combustion test, bluish sharp flames are observed. Ifthe gaseous substance is merely a gas mixture consisting of OHMASA-GASand carbon dioxide, colorless flames should be observed judging frompreviously performed combustion test results of OHMASA-GAS. However, inthe present embodiment, since bluish sharp flames are observed when thegaseous substance obtained in embodiment 1 is burnt, it is obvious thatOHMASA-GAS chemically reacts with carbon dioxide, and that a new fuelgas consisting of carbon, hydrogen and oxygen is produced as a result ofthe chemical reaction. Combustion temperatures of the gaseous substanceare in a range of 300° C.-500° C., and the combustion test is performedsafely and stably.

Embodiment 3

After a gas mixture consisting of carbon dioxide and OHMASA-GAS withmixture ratio 70:30, 50:50 or 30:70 is filled in the high pressure glasstube used in embodiment 1, the filled gas mixture is compressed up to 1MPa gauge pressure and 1.5 MPa gauge pressure. No liquid such aswaterdrops and steam are observed in the compressed high pressure glasstube, so that only gaseous substance exists in the glass tube.

Judging from the above mentioned observed facts, it is confirmed that noliquid substances are observed and only gaseous substance exists in theabove mentioned mixture ratio range and compressed pressure range.

Embodiment 4

Combustion tests are performed by burning the gaseous substancesobtained in embodiment 3 with the burner, 15 minutes, a week or a monthafter the gaseous substance is produced in embodiment 3. In thecombustion tests, bluish sharp flames are observed as in embodiment 2,and there are no differences in the observed facts regardless of timeselapsed after the gaseous substances are produced.

Embodiment 5

In the same conditions as in embodiment 3, a temperature of the highpressure glass tube containing gaseous substance is changed at 5° C.,15° C. or 30° C. But no liquid such as waterdrops and steam are observedin the compressed high pressure glass tube, so that only gaseoussubstance exists in the high pressure glass tube.

Embodiment 6

0.1-5% of fossil fuel containing propane and methane, 20-50% of carbondioxide and the balance of OHMASA-GAS are mixed and are reacted witheach other. Bluish flames are observed when the combustion test isperformed on the reaction product. From the observed facts, combustionof carbon is confirmed. It is confirmed that an optimal mixture ratio is0.5% of fossil fuel containing propane and methane, 35% of carbondioxide and the balance of OHMASA-GAS.

In the above described embodiments, the gas mixtures are reacted in thehigh pressure glass tube and reaction products are stored in the highpressure glass tube. However, even when the reaction products are storedin stainless steel containers or in steel containers, the containers arestable without any changes.

Embodiment 7

In the same way as in embodiment 3, combustion tests are performed bychanging mixing ratios between carbon dioxide and OHMASA-GAS and testresults are compared. As a result, optimal combustion is attained in themixing ratio consisting of 10-50% of carbon dioxide and 90-50% ofOHMASA-GAS.

Generated heat quantities in two ratios are as follows.

-   -   (1) Carbon dioxide: 20% OHMASA-GAS: 80% 44.8 MJ/m³ (10,700        Kcal/m³)    -   (2) Carbon dioxide: 40% OHMASA-GAS: 60% 43.9 MJ/m³ (10,500        Kcal/m³)

The heat quantities are measured by generally performed methods in gascombustions.

As described in embodiments, since it is confirmed that the new fuel gasis produced by reacting carbon oxide with OHMASA-GAS, it becomespossible to construct a carbon dioxide reduction system by combining anOHMASA-GAS production apparatus. The carbon dioxide reduction systemcomprises the OHMASA-GAS production apparatus and a gas mixing tank(cushion tank). The gas mixing tank receives OHMASA-GAS from theproduction apparatus and 10-50% of exhaust gas from gas combustionmachines (engine, boiler and the like) outside, and therein the new fuelgas can be synthesized by reacting carbon dioxide with OHMASA-GAS.

Further, it is possible to synthesize the new fuel gas by blowing carbondioxide directly onto platinum electrodes in electrolysis vessels of theOAMASA-GAS production apparatus without using the gas mixing tank, suchthat blowing amount of carbon dioxide is determined so as to adjust themixing ratio consisting of 10-50% of carbon dioxide and 90-50% ofOHMASA-GAS.

And further, a combustible gas or a mixture gas consisting of thecombustible gas and OHMASA-GAS is combusted as a fuel for generators,boilers, cars or the like, and carbon dioxide in the exhaust gasgenerated by the combustion is reacted with OHMASA-GAS again so as toproduce the new fuel gas, so that it is possible to construct a systemwhich almost prevent newly generated carbon dioxide from exhausting intothe atmosphere.

Thus carbon dioxide is reused and reduced by these systems mentionedabove, so that inexpensive heat sources may be obtained.

INDUSTRIAL APPLICABILITY

Since the new fuel gas of the present invention obtained by reactingcarbon dioxide with OHMASA-GAS is not dangerous to explode or the like,the new fuel gas may be replaced with conventionally used fossil fuelsas fuels for domestic uses, cars and ships or may be widely used bymixing the fossil fuels.
